Buying Guide
- Infestation level: For heavy infestations, consider larger gallon sizes (1 gallon or more) and products designed for long-lasting action.
- Drain types: If you have multiple drains (kitchens, bathrooms, disposals), multi-drain kits or larger bottles help reduce the frequency of restocking.
- Formulation: All-natural or microbial formulas are gentler on plumbing and the environment, but may require more time for visible results.
- Space and storage: Large containers require practical storage space; plan for safe, dry storage away from children and pets.
- Application routine: Anti-glug features and simple pouring are beneficial for nightly or low-usage windows when flies are most active.
- Safety and compatibility: Check septic-system compatibility if applicable and avoid using near food prep surfaces during application.
